I heard that yahoo uses google's index for search results. Is that correct? Is it more complex than just using google's index if that is true.

Hmm, open up one browser window for Google, open up another browser window for Yahooo!. Type the same search query into both search boxes. Compare.

Digitalhost,

With the current dance, he could face totally different SERPs. :)

Yes, Yahoo! uses Google search results. But as Yahoo! acquired Inktomy recently, this could -and probably will- change in the future.

I’m not convinced that they use just google results. I’m on page 1 for my KW’s in yahoo and page 2 on google and it has been that way for sometime now.

He could, but I doubt it. The 17 people that I check with on a daily basis seem to see the same thing I see and between us we live in 15 countries and 5 continents.

Yahoo first searches it's own directory for results and if it does not find any matches then the Secondary Index is provided by google. HTH.

BTW that is going to change as it is rumoured that Yahoo! will switch over to Inktomi index by year end.

I dont want to nit pick here, but there are a few exceptions. Not all Yahoos currently use the Google index for primary results. For instance, the French Canadian Yahoo still use the directory database firs and pick on Google for secondary results.

Strange. For the most part, Yahoo and Google results always seemed to mirror each other. Today, I did a search for one of my keywords and the Google results didn't start until #11. The top 10 were from somewhere else. Maybe Inktomi results?

I think you are right. I thought it had something to do with their directory based on what I've seen with my own site anyway.

They don't use Google results, they use Google's index and ranking system. Two major differences that will cause you to move from page 2 to page 1 when going from Google to Yahoo! are
1. Yahoo! has a default of 20 results per page. Google's is 10.
2. There are no indented results on Y!

It's actually possible to move from page three to 1 as a result of these.

It's not just a page thing. It's the top of page1 and the bottom of page 2.

More likely www-sj results were showing either on Google.com or Yahoo.com at the time.

I believe Yahoo takes the basic Google results and then adjusts them using additional filters. Most of the time they will appear similar, but one filter in particular I am monitoring reduces the importance of backlinks/anchor text at Yahoo.

Yahoo also appears to have filters for adjusting SERPs based on Yahoo directory entries.

To see an interesting and large difference between the two try searching for God. Many other very common keywords/phases show similar differences.

These differences are nothing to do with the update, they have been there for sometime.

OMG this is like a bad dream. The point is, Mattricks can open up two browser windows and try to answer the question, or we can all discuss the myriad differences between French Canadian Yahoo and U.S. Yahoo and how Yahoo applies whatever they apply to Google's results and answer NO ONEs question.

Sorry Mattricks, but if you're searching Yahoo! from Pakistan or Jordan or Islamabad, your results may vary from someone searching from Ohio or Tunisia or Ireland. However, you're then at the mercy of contacting people that live in those areas to check the positions of the phrases you are searching for, or you can open up two browser windows and check the results that are relevant for you.

So to answer your question fully, yes, Yahoo uses Google search results, and yes, it is more complex than that.

That also makes sense since backlinks is why I fell from the top 3 spots on google.

Thats unbelievable. This must be the new index though because while I believe what you say percentages (that its been this way for some time) I must be looking at the -sj or -cw index because the Google results are not good at all.

I would not get worried about the god example that looks manually edited to me.

Somebody influential in yahoo seems to fear god and does not dare to serve with strange results.

google does not seem to have this problem....

The God example has been that way for over a month...nothing to do with the update. Try it on all data centers, it is the same (or was a couple of mins ago).

What scares me is that I have found over 30 very, very common terms where Yahoo results differ significantly. By scares I mean Yahoo is much better in almost all of cases (unbiased opinion, no searches were in my cats).

The God example is an extreme case of someone wanting to prove they can rank high using backlinks/anchor text only. True proof that site content doesn't always matter!
But the other sites aren't playing these tricks, it is caused by the algo differences.

well for what I have checked during Dominic...I admit it was not that much and it was an uncompetitive term...yahoo seemed to be the google -ex data center.

The only difference I noticed before dominic is that yahoo eliminated double listings of URLs and -ex is doing just that now.

results of yahoo only were always shown as separate on top.

but if they hand edit the search for god there are bound to be more examples like that.
